My zero Wi-Fi is not working

Zero Series
56

If using NetworkManager you can turn off power save mode by doing the following:

sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/g' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

If using ifupdown, add the following to the /etc/network/interfaces file

allow-hotplug wlan0
iface wlan0 inet dhcp
	wireless-power off # <-- turn off power save mode
	wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
